You must work together, using the information that has been provided for you in the attached information packets, and decide what action(s) should be taken to control the measles outbreak currently plaguing your city, Baltyre. Your actions should be evidence-based – use the peer-reviewed literature to decide on measures that will stop the pandemic in your scenario.

Your action points may include directives to gather more information (e.g., contact tracing of current cases, microbiological testing of food/water, etc.), or specific directives (e.g. public health measures, non-pharmaceutical interventions, etc.). Use the data/expertise of all group members. Be clear, concise, and specific.

You should submit 3-5 specific actions to control the pandemic, using the workshop 3 pro forma (available on MyPlace). Submit this by noon, Friday March 10th, via the submission link on MyPlace.

Dear Provost,

I am outraged to hear about this new pandemic in Baltyre. There seems to be no end to the suffering that pandemics inflict on our city in these days.

I wish that your office is going to do something about tragedy as soon as possible.

Dear Provost,

This new pandemic in Baltyre has the potential to destroy our businesses. I run a restaurant on the high street and almost went bankrupt due to COVID.

I hope you realise that you need to put businesses first now - we were unfairly forced to bear the costs of the last pandemic.

I hope very much that your office is going to do something about dreadful state of affairs at once, keeping in mind the economic interests of businesses in our city and the fact that we cannot afford restrictions that cripple our businesses.

Sincerely,
Ailidh (The Baltyre Shop, proprietor)

Subject: New Pandemic Measures

Dear Provost,

I dread that you and your office are going to use this new pandemic as yet another excuse for government overreach into citizens’ lives. Machiavelli said that power corrupts absolutely, and he was absolutely right - look at what happened during the last pandemic.

Facemasks are just the tyranny of the minority over the majority, I hope that you will not permit them again on your watch.

Respectfully,
Ailidh (a concerned voter)

Dear Provost,

I have just learned that my my nephew has passed away due to the new pandemic in Baltyre. This is especially terrible coming hard on the heels of all of our losses due to COVID-19.

This is especially terrible coming hard on the heels of all of our losses due to COVID-19.

I hope that, considering how many other families have also lost loved ones, that you and your office will be doing everything in their power to halt this pandemic and prevent more needless deaths.

Respectfully,
Roman
